Hello, people! Can someone help me?

I am trying to package TDE for NixOS [1], but I'm stuck in tdelibs
[2]. It complains about a "general.entities" file not being updated. I
googled the error but there is no pages about that issue. I have
almost no idea what I can do here.

Here is a pastebin : http://termbin.com/4tnd
